There is currently no open public access to Lake Katrina. It is located just north of Hwy 12 in Maple Plain and can be accessed through Baker Park Reserve. Three Rivers Parks District maintains a canoe landing on the northern side of the lake, which can be accessed through a gated road.
Lake Katrina is a class 2B lake protected for aquatic life and recreation. MCWD staff has been monitoring the lake once a month from May through September since 2006.
Currently not available.
Monitoring season duration was from May through September. Surface samples were collected once a month throughout the season and the parameters analyzed include: total phosphorus (TP) and chlorophyll-a. Measurements of Secchi disc depth were also recorded.
| 2008 Summer Water Quality Summary |
| Parameters | Range | Mean | TSI Value | Lake Grade |
| Months | June - Sept. | May - Sept. | ||
| Secchi Depth (m) | 0.2 - 0.8 | 0.4 | 72 | F |
| Surface TP (µg/L) | 115 - 505 | 235 | 85 | F |
| Chlorophyll-a (µg/L) | 42 - 368 | 124.6 | 80 | F |
| Overall Score | 79 | F |
The following summary refers to Figure 10.3 (a-c).
- Secchi disk depth was below the standard (> 1.2 m) for the entire season. In the beginning of the season, secchi disk depth increased from 0.3 m to 0.8 m. July to September, secchi disk depth ranged from 0.2 m to 0.4 m.
- From May to August, chlorophyll-a increased in concentration from 8 µg/L to 368 µg/L (standard < 15 µg/L). Chlorophyll-a concentrations decreased to 109 µg/L in September.
- Surface TP concentrations gradually increased over the entire season with concentrations above the standard (< 40 µg/L). In September, concentrations were about 12 times higher than the standard (505 µg/L).
